Figure 13.8 shows plot of PV//T versus P for l.OOxxlO^-3 kg of oxygen gas at two different temperatures.Which is true: T_1 > T_2 or T_1

The figure VSAQ 29 shows a plot of three curves a,b,c, showing the variation of photocurrent in collector plate potential for three different intensities I_1 , I_2 and I_3 having frequencies v_1 , v_2 and v_3 respectively incident on a photosensitive surface. Point out the two curves for which the incident raidations have the same frequency but different intensities.

Two curves C_1: y=x^2-3\ a n d\ C_2\ : y\ k x^2\ ,\ k in R intersect each other at two different points. The tangent drawn to C_2 at one of the points of intersection A\ -= (a , y_1),(a >0) meets C_1 again at B\ (1, y_2)\ (y_1!=y_2)dot The value of ' a ' is 1 (b) 3 (c) 5 (d) 7

Two parabolas C and D intersect at two different points, where C is y =x^2-3 and D is y=kx^2 . The intersection at which the x value is positive is designated Point A, and x=a at this intersection the tangent line l at A to the curve D intersects curve C at point B , other than A. IF x-value of point B is 1, then a equal to

Two narrow bores of diameters 3.0 mm and 6.0 mm are joined together to form a U-tube open at both ends. If the U-tube contains water, what is the difference in its levels in the two limbs of the tube ? Surface tension of water at the temperature of the experiment is 7.3xx 10^-2 N m^-1 '. Take the angle of contact to be zero and density of water to be 1.0xx 10^3 kg m^- 3 ( g = 9.8 m s^-2 ) .

The figures SAQ 13(a) shows a bar magnet M falling under gravity through an air cored coil. Plot a graph showing variation of induced e.m.f. with time(t). What does the area encloed by E-t curve depict?

At any two points of the curve represented parametrically by x=a (2 cos t- cos 2t);y = a (2 sin t - sin 2t) the tangents are parallel to the axis of x corresponding to the values of the parameter t differing from each other by :

A open ended mercury manometer is used to measure the pressure exerted by a trapped gas as shown in the figure. Initially manometer shows no difference in mercury level in both columns as shown in diagram. After sparking 'A' dissociates according to following reaction 2A(g)rarr 3B(g)+2C(g) If pressure of Gas "A" dissociates to 0.8 atm, then (Assume temperature to be constant and is 300 K)

A straight line L through the origin meets the lines x + y = 1 and x + y = 3 at P and Q respectively. Through P and Q two Straight lines L_1 and L_2 are drawn parallel to 2x- y=5 and 3x+y=5 respectively. Lines L_1 and L_2 intersect at R. Show that the locus of R, as L varies, is a straight line.
